Description of CD152 Recombinant Protein

General information on CD152 Recombinant Protein:

CD152, also known as CTLA4 and cytotoxic T lymphocyte protein 4, is a single-pass type I membrane protein and a member of the immunoglobulin superfamily. It is the second member of the CD28 receptor. The ligands or counterreceptors of these two proteins belong to the B7, CD8 (B7-1) and CD86 (B7-2) families. CTLA4 delivers inhibitory signals to T lymphocytes, while CD28 delivers stimulatory signals. Intracellular CTLA4 is also present in regulatory T cells and may play an important role in its function. CD152 antigen or cytotoxic T lymphocytes (CTLA-4) are important receptors involved in downregulating T-cell activation. Due to its far-reaching inhibitory effect, CD152 is considered a candidate solid acceptable for autoimmunity and a convincing target for cancer immunotherapy. In particular, recent evidence suggests that CD152 is also important in homeostasis and the function of population suppressor cells called regulatory T cells (Treg).
